Medchemexpress LLC 4-Nitrophenyl phosph 50mg | 330-13-2 | 219.09 g·mol⁻1 | C6H6NO6P | 50 MG
4-nitrophenyl phosphate is an aryl phosphate chromogenic substrate used to measure phosphatase activity. Enzymatic hydrolysis yields 4-nitrophenolate, producing a yellow color quantified by absorbance (commonly at 405 nm). It is supplied as a solid suitable for assay development, enzyme kinetics, and biochemical research.
- Produces a measurable yellow 4-nitrophenolate upon hydrolysis (absorbance ~405 nm).
- Suitable for alkaline, acid, and tyrosine phosphatase activity assays.
- High reported purity (99.48%), minimizing assay interference.
- Solid form for convenient handling in microplate and cuvette assays.
- Includes standard chemical identifiers (CAS 330-13-2, formula C6H6NO6P).
