Chemical Structure
Description
As a certified reference material (CRM), S-(1-Vinyl-1H-pyrazolo[3,4-b]pyrazin-5-yl) dodecanethioate 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.
S-(1-Vinyl-1H-pyrazolo[3,4-b]pyrazin-5-yl) dodecanethioate (CAS 133280-17-8), molecular formula C19H28N4OS and molecular weight 360.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of S-(1-Vinyl-1H-pyrazolo[3,4-b]pyrazin-5-yl) dodecanethioate (C19H28N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
