C Peptide Mots Specifications Purity Certification Manufacturing Sourcing Guide for Labs

Core Molecular Specs & Technical Index

Mots c peptide is a 16-amino-acid mitochondrial-derived peptide that has gained significant traction in advanced cosmetic formulation and laboratory research. For B2B buyers—including raw material distributors, contract manufacturers, and R&D labs—understanding the precise technical specifications is the first step toward ensuring batch consistency and regulatory compliance. The core value of mots c peptide lies in its ability to support cellular energy metabolism and mitochondrial function, making it a high-demand ingredient in anti-aging and regenerative product lines.

• Molecular Weight: 2174.5 Da (monoisotopic mass), ensuring precise dosing in formulation.
• Purity Standard: ≥98% by HPLC (High-Performance Liquid Chromatography), with 99%+ available for premium-grade orders.
• Solubility: Fully soluble in water and PBS buffer at 1 mg/mL; recommended solvent for stock solutions is sterile deionized water.
• Storage Conditions: Lyophilized powder stable at -20°C for 24 months; reconstituted solution must be used within 7 days at 4°C.
• Appearance: White to off-white lyophilized powder, free of visible aggregates or discoloration.

Industry data from the Peptide Therapeutics Foundation indicates that labs sourcing mots c peptide with ≥98% purity achieve 40% higher reproducibility in mitochondrial function assays compared to those using lower-grade alternatives. This underscores the critical role of purity in research outcomes.

Manufacturing & Quality Control

The production of mots c peptide follows a rigorous solid-phase peptide synthesis (SPPS) process, typically using Fmoc chemistry. This method ensures high coupling efficiency and minimal side reactions. After synthesis, the crude peptide undergoes cleavage and deprotection, followed by purification via preparative HPLC. Quality control is multi-layered, involving both in-process checks and final batch release testing.

Purification & Analytical Methods

Reversed-phase HPLC is the primary purification technique, achieving baseline separation of the target peptide from truncated sequences and deletion impurities. Each batch is then subjected to mass spectrometry (MS) for molecular weight confirmation and amino acid analysis (AAA) for composition verification. Additional tests include endotoxin levels (≤1 EU/mg), bioburden (sterile filtration), and residual solvent analysis per ICH Q3C guidelines.

Certification & Compliance

• Certificate of Analysis (CoA): Provided with every batch, detailing HPLC purity, MS data, and physical properties.
• MSDS (Material Safety Data Sheet): Available for safe handling and transportation.
• GMP Compliance: Manufacturing facilities adhere to current Good Manufacturing Practices (cGMP) for pharmaceutical intermediates.
• Third-Party Testing: Independent lab verification for heavy metals (Pb, As, Cd, Hg) and microbial limits.
• Stability Data: Accelerated stability studies at 40°C/75% RH for 6 months confirm shelf life.

Commercial Application Scenarios

Mots c peptide is utilized across three primary B2B channels, each with distinct requirements for purity, packaging, and documentation.

Cosmetic Formulation

In high-end skincare, mots c peptide is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1%. Formulators require water-soluble, low-endotoxin peptides that integrate seamlessly with other active ingredients. The peptide supports mitochondrial biogenesis in skin cells, contributing to improved dermal density and elasticity. Bulk orders typically range from 10 grams to 1 kilogram, with custom blending available.

Laboratory Research

Academic and biotech labs use mots c peptide for in vitro studies on cellular senescence, metabolic disorders, and mitochondrial dynamics. Researchers demand consistent purity across batches, with detailed analytical data for publication. Common pack sizes are 5 mg, 10 mg, and 50 mg vials, often supplied with a CoA and MSDS.

Bulk Wholesale Distribution

Distributors and contract manufacturers require large-scale supply (100 grams to 10 kilograms) with competitive pricing and reliable logistics. Key considerations include lead time (typically 2–4 weeks), custom labeling, and temperature-controlled shipping. Many buyers also request stability data and regulatory support for international customs clearance.

Bulk Purchase Selection Guide

When sourcing mots c peptide in bulk, buyers must navigate common pitfalls to ensure they receive a product that meets their specifications. The following guide outlines key selection standards and a practical checklist.

Common Pitfalls

• Inaccurate Purity Claims: Some suppliers quote "≥95%" but deliver material with 80% purity. Always request a CoA with HPLC chromatogram.
• Improper Storage: Peptides shipped without dry ice or cold packs may degrade during transit, reducing activity.
• Hidden Costs: Low per-gram prices often exclude shipping, customs duties, or documentation fees.

Selection Standards

• Purity Verification: Insist on HPLC and MS data for every batch.
• Packaging Integrity: Lyophilized powder in vacuum-sealed vials with desiccant.
• Supplier Transparency: Look for manufacturers that provide batch-specific CoAs and are open to third-party audits.

Buyer Checklist

• Confirm minimum order quantity (MOQ) and lead time.
• Request a sample (1–5 mg) for in-house testing before bulk purchase.
• Verify shipping conditions: dry ice for international orders.
• Check for regulatory documentation (MSDS, origin certificate).
• Evaluate supplier responsiveness and technical support.

Frequently Asked Questions

Q1: What is the typical lead time for bulk orders of mots c peptide?
Standard lead time is 2–4 weeks for orders up to 1 kilogram, depending on current production schedule and purity requirements. Rush orders can be accommodated with prior arrangement. We recommend placing orders at least 3 weeks in advance to ensure timely delivery.

Q2: How do you verify the purity of mots c peptide before shipment?
Every batch undergoes HPLC analysis with a UV detector at 214 nm and 280 nm. The chromatogram is included in the Certificate of Analysis, showing the main peak area percentage and any impurity peaks. Additionally, mass spectrometry confirms the molecular weight within ±0.5 Da.

Q3: Can mots c peptide be used in cosmetic formulations with other active ingredients?
Yes, mots c peptide is compatible with most water-soluble actives, including hyaluronic acid, vitamin C, and other peptides. However, we recommend conducting a stability test at the intended formulation pH (optimal range 5.0–7.0) to ensure no precipitation or degradation. Our technical team can provide guidance on formulation protocols.
