Chemical Structure

N-tert-Butylbenzohydrazide CAS 99981-48-3 chemical structure

Description

As a certified reference material (CRM), N-tert-Butylbenzohydrazide 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.

N-tert-Butylbenzohydrazide (CAS 99981-48-3), molecular formula C11H16N2O and molecular weight 192.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-tert-Butylbenzohydrazide (C11H16N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 192.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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