Firstly, following the reported procedure, these phenols reacted with methyl chloroacetate
under microwave irradiation and phase-transfer catalysis conditions to synthesize p-substituted phenoxyacetates that was then hydrolyzed to get corresponding phenoxyacetic acid compounds (a1-a5).

The azo dye coupling methods were used for acid phosphatase and alkaline phosphatase, with naphthol AS-BI phosphate and [alpha]-naphthol phosphate as substrates, and for non-specific esterases, with the substrates [alpha]-naphthyl acetate, naphthyl AS-D chloroacetate
, and Tween-80 (DifCo), as described in Bancroft and Hand (1987).
The cytochemistry of both forms of M3 shows characteristic strong positivity for peroxidase or Sudan Black B and for chloroacetate
21) [included Sudan-black, specific esterase (Alfa-naphthyl ASD chloroacetate
esterase), non-specific esterase (Alfa-naphthyl butyrate esterase), Periodic acid-Schiff, and acid phosphatase.
Mast cells are also rich in chloroacetate
esterase, but histologic identification of that enzyme is also seen in neutrophilic myelocytes.
Mast cells were detected by chloroacetate
esterase (CAE) staining according to published protocols of mast cell detection (Beckstead et al.
Many bacteria strains that possess inducible dehalogenases have ability to cleave off carbon-halogen bond in chloroacetate
were isolated from soil (Hardman and Slater, 1981; Ismail et al.
In our previous work we studied the kinetics of pH-independent hydrolysis of 4-nitrophenyl chloroacetate
(4-NPCA) under ultrasound by using a spectrophotometric method .
03 mol) of ethyl chloroacetate
drop wise with continuous stirring to get clear solution.
The clinician should be alerted to the possibility of this diagnosis by a finding of a less differentiated neoplasm combined with pathologic evidence of myeloid differentiation in the presence of positive testing for chloroacetate
esterase, myeloperoxidase, lysozyme, CD43, CD79a, or CD3.
The histopathologic review of the skin biopsy confirmed the diagnosis of LC in this case, with negative CD20 cell marker and positive chloroacetate
esterase reaction and lysozyme markers (9,11-12).
