  The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

  Chemically reactive carbocyanine dyes incorporating an indolium ring moiety that is substituted at the 3-position by a reactive group or by a conjugated substance, and their uses, are described. Conjugation through this position results in spectral properties that are uniformly superior to those of conjugates of spectrally similar dyes wherein attachment is at a different position. The invention includes derivative compounds having one or more benzo nitrogens.

  化学反应性碳氰染料包含一个在3位被反应性基团或共轭物质取代的吲哚环部分，并描述了它们的用途。通过这个位置的共轭导致光谱特性均优于在不同位置附着的光谱相似染料的共轭物。该发明包括具有一个或多个苯并氮的衍生化合物。

  Disclosed are cyanine dyes that are useful for labelling and detecting biological and other materials. The dyes are of formula (I): in which at least one of groups R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 R 11 , R 12 , R 13 and R 14 is -L-M or -L-P, where L is a linking group, M is a target bonding group and P is a conjugated component, and at least one of groups R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 and R 10 comprises fluorine. The use of cyanine dyes substituted by fluorine and having additional substitution with three or more sulphonic acid groups for labelling biological target molecules results in a labelled product in which there is reduced dye-dye aggregation and improved photostability, compared with cyanine dyes having no such substitutions. The dyes of the present invention are particularly useful in assays involving fluorescence detection where continual or repeated excitation is a requirement, for example in kinetic studies, or in microarray analyses where microarray slides may need to be reanalysed over a period of days.

  揭示了一种对于标记和检测生物和其他材料有用的青霉素染料。该染料的化学式为（I）：其中R1、R2、R3、R4、R5、R6、R7、R8、R9、R10、R11、R12、R13和R14中的至少一个是-L-M或-L-P，其中L是连接基团，M是目标键合基团，P是共轭组分，并且R3、R4、R5、R6、R7、R8、R9和R10中的至少一个包含氟。通过用氟取代并具有三个或更多磺酸基团的青霉素染料标记生物靶分子，得到的标记产品中减少了染料-染料聚集并提高了光稳定性，与没有这种取代的青霉素染料相比。本发明的染料在涉及荧光检测的分析中特别有用，其中需要连续或重复激发，例如在动力学研究中，或在微阵列分析中，微阵列玻片可能需要在数天内重新分析。
