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 CRW4NIT4W1 13640-26-1 Pimprinine 1H-Indole, 3-(2-methyl-5-oxazolyl)- 5,3'-Indolyl-2-methyloxazole NSC 80793 UNII-CRW4NIT4W1.
CATO supplies CRW4NIT4W1 13640-26-1 Pimprinine 1H-Indole, 3-(2-methyl-5-oxazolyl)- 5,3'-Indolyl-2-methyloxazole NSC 80793 UNII-CRW4NIT4W1 (CAS 13640-26-1), a certified reference material (molecular formula C12H10N2O, MW 198.22 g/mol) for analytical method development and quality control.
The molecular framework of CRW4NIT4W1 13640-26-1 Pimprinine 1H-Indole, 3-(2-methyl-5-oxazolyl)- 5,3'-Indolyl-2-methyloxazole NSC 80793 UNII-CRW4NIT4W1 (C12H10N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures CRW4NIT4W1 13640-26-1 Pimprinine 1H-Indole, 3-(2-methyl-5-oxazolyl)- 5,3'-Indolyl-2-methyloxazole NSC 80793 UNII-CRW4NIT4W1 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
