Chemical Structure

H-Val-Arg-Lys-Arg-Thr-Leu-Arg-Arg-Leu-OH CAS 105802-82-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including H-Val-Arg-Lys-Arg-Thr-Leu-Arg-Arg-Leu-OH.

H-Val-Arg-Lys-Arg-Thr-Leu-Arg-Arg-Leu-OH (CAS 105802-82-2) is a high-purity analytical reference standard with the molecular formula C51H100N22O11 and a molecular weight of 1197.50 g/mol.

H-Val-Arg-Lys-Arg-Thr-Leu-Arg-Arg-Leu-OH (C51H100N22O11) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), H-Val-Arg-Lys-Arg-Thr-Leu-Arg-Arg-Leu-OH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
