Description
D-Ser-8-Semaglutide is a pharmaceutical impurity reference standard related to Semaglutide, molecular formula C187H291N45O59 (expected by analogy to sibling rows; not independently sourced for this specific compound -- see Open Items), molecular weight 4113.64 (expected by analogy; see Open Items). Identified industry-wide by amino-acid sequence rather than by a CAS number (sequence not published -- no direct source found). Allas Chem Tech, a Bangalore-based manufacturer and supplier of pharmaceutical reference standards, carries this material in 50 mg packs at Rs.99000/-, supplied with a certificate of analysis and complete characterisation data.

Analytical applications
D-Ser-8-Semaglutide is used in analytical method development and method validation (AMV), and in Quality Control (QC) applications supporting Abbreviated New Drug Applications (ANDA) and commercial production of semaglutide.
STRONG FLAG: zero third-party corroboration found under this exact name
STRONG FLAG: zero third-party corroboration found for a "D-Ser-8-Semaglutide" impurity across targeted searches of Daicel, SynZeal, Clearsynth, Pharmaffiliates and KM Pharma. A D-Ser-8 impurity of Tirzepatide (a different GLP-1 peptide) was the only close match found, and is not this compound. By analogy to the other single-point D-isomer impurities in this run (rows 249, 250, 253), a D-Ser-8 impurity of Semaglutide would be expected to share Semaglutide's own formula/MW (C187H291N45O59, 4113.64) -- shown above as an analogy-based estimate, NOT a sourced fact. Recommend priority chemist review before this page goes live.
Quality control and regulatory filings
The standard supports routine QC release testing of semaglutide drug substance and drug product, and is used to generate impurity data submitted in ANDA and DMF applications. Full characterisation data accompanies every batch for direct citation in regulatory documentation.
Documentation supplied
Every order of D-Ser-8-Semaglutide ships with a Certificate of Analysis (COA), 1H NMR, 13C NMR, Mass/LC-MS, HPLC, FT-IR and TGA potency data. An MSDS, a Structure Elucidation Report and 2D NMR (COSY, HSQC, HMBC) are available on request.
Synonyms and alternate designations
Full chemical/IUPAC name: Identified industry-wide by amino-acid sequence rather than by a CAS number (sequence not published -- no direct source found). No confirmed synonym is cited here: the only related listing found is a D-Ser-8 impurity of Tirzepatide, a chemically distinct peptide, not this material -- see the STRONG FLAG above and Open Items.
Frequently asked questions
What is the CAS number of D-Ser-8-Semaglutide?
D-Ser-8-Semaglutide does not currently have an assigned CAS Registry Number; it is identified industry-wide by amino-acid sequence rather than CAS number.
