NINGBO INNO PHARMCHEM CO.,LTD. is proud to contribute to the field of forensic science by providing Ninhydrin Hydrate (CAS: 485-47-2), a reagent with a profound impact on crime scene investigation. Its primary function revolves around the intricate ninhydrin amino acid reaction, which is essential for visualizing latent fingerprints on various surfaces, particularly those that are porous.

The magic of Ninhydrin Hydrate lies in its reactivity with primary and secondary amines, which are abundant in human perspiration. When applied to a surface, Ninhydrin Hydrate reacts with these amino acids to produce a characteristic color. This color, typically a vibrant purple, is known as Ruhmann's purple. The intensity and clarity of this color are what make ninhydrin hydrate fingerprint development so effective. It allows forensic examiners to readily identify and lift fingerprints from items such as paper documents, envelopes, and cardboard, making it a staple in the arsenal of forensic fingerprint analysis chemicals.

One of the most compelling aspects of Ninhydrin Hydrate is its efficacy in developing latent fingerprints on paper, even those that are old. Amino acids have a natural affinity for cellulose, the primary component of paper, which helps to anchor them to the surface. This stability means that prints deposited years ago can still be developed successfully using Ninhydrin Hydrate. This capability is invaluable, as it allows investigators to revisit cold cases or analyze older evidence with a reasonable expectation of recovering crucial fingerprint data.

While newer technologies and reagents, such as DFO and IR powders, have emerged in forensic science, Ninhydrin Hydrate remains a fundamental tool. When considering the comparative strengths of ninhydrin vs dfo fingerprinting, it's often found that a combination of methods yields the best results. Ninhydrin offers a direct visual cue, whereas DFO provides fluorescence under specific lighting conditions. As a versatile amino acid detection reagent, Ninhydrin Hydrate's role is irreplaceable in many investigative protocols.

NINGBO INNO PHARMCHEM CO.,LTD. is committed to ensuring the availability of high-quality Ninhydrin Hydrate. Our product meets the stringent requirements of forensic laboratories, enabling investigators to perform their vital work with confidence. The reliable performance of Ninhydrin Hydrate in developing clear, visible fingerprints underscores its continued importance in the pursuit of justice and the resolution of criminal cases.
