Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies (D-Lys(nicotinoyl)1,β-(3-pyridyl)-Ala3,3,4-dichloro-D-Phe5,Asn6,D-Trp7·9,Nle11)-Substance P (CAS 129176-97-2), a certified reference material (molecular formula C86H104Cl2N18O13, MW 1668.76 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (D-Lys(nicotinoyl)1,β-(3-pyridyl)-Ala3,3,4-dichloro-D-Phe5,Asn6,D-Trp7·9,Nle11)-Substance P is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1668.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
