《An incisive optical recognition of monohydrogen phosphate by a fluorescein-based chemodosimeter》 was written by Asthana, Sharad Kumar; Pandey, Abha; Kumar, Ajit; Upadhyay, K. K.. COA of Formula: C3H3ClO3 And the article was included in New Journal of Chemistry in 2020. The article conveys some information:
Numerous methods for the determination of phosphates (H2PO4-, HPO42-, PO43-, PPi) are described in the literature. However, the design of optical probes which are able to recognize specifically monohydrogen phosphate (MHP) ions, i.e. HPO42-, has been rarely considered. We herein devised an incisive chemodosimeter (FLH) for detecting HPO42- over other phosphates successfully. In the experiment, the researchers used Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3COA of Formula: C3H3ClO3)
Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.COA of Formula: C3H3ClO3
