Peptide reference standards
Also known as: certified reference material · CRM
Characterised materials of known identity and assigned purity, used to calibrate analytical methods and to confirm the identity of test articles by comparison.
Development status: Laboratory research reagent
Identifiers and molecular characteristics
- CAS number
- Not verified
- Molecular formula
- Not verified
- Molecular mass
- Not verified
- Amino-acid sequence
- Not verified
- PubChem CID
- Not verified
Identifiers are published only with a source and a check date. Fields marked “not verified” have not yet been confirmed against a primary source — we show the gap rather than an unchecked figure. Always confirm against the certificate of analysis for the specific lot you hold.
Biological targets
- Not applicable — these are measurement materials
Mechanism of action
Not applicable. A reference standard’s value lies in the rigour of its characterisation and the traceability of its assigned values, not in any biological activity.
Research evidence and its limits
Governed by metrological guidance rather than biomedical literature. ISO 17034 covers reference material producers; pharmacopoeial standards are issued by bodies such as the USP, Ph. Eur. and the Indian Pharmacopoeia Commission.
Safety considerations
No regulatory authority has assessed this compound as safe or effective for any human indication. The published record is predominantly laboratory and animal work, which does not establish human safety. Supplied and discussed here strictly as a laboratory research material. Not a medicine, not for human or veterinary administration, and nothing on this page should be read as a dosing, treatment or safety recommendation.
Analytical identification and quality testing
Identity by high-resolution mass spectrometry against the expected mass, purity by RP-HPLC with UV detection. Tandem MS sequencing or peptide mapping gives stronger identity evidence than mass alone.
Regulatory status
Reference standards are regulated as measurement materials, not medicines.
Frequently asked questions
Why does a reference standard matter for identity testing?
Because a mass measurement alone cannot distinguish a compound from an isomer or a close analogue. Co-elution and spectral match against a characterised standard is far stronger evidence that what you have is what the label says.
